We have published beta versions of RRC-Micro(1.10.0), 1274B(2) and RRC-1258(2.91) that add support for CW using external paddles connected to the 1274 USB Dongle's AUX connector. If you would like to give it a try then you need to upgrade 1274B's and radio RRC-1258's firmware in addition to upgrade the RRC-Micro software.

The keyer/CW function must also be enabled in RRC-Micro. That is done on a new tab called 'Keyer':

The side tone is locally generated in the PC and can be tested that it works by clicking the "Toggle tone" button. When sending CW there might be a 'click' sound at the beginning and the end of the tone. It's caused by how the PC starts and stops playing the 'beep' and is not possible to eliminate.

LF delay is used to cancel echo from the CW transmission in the radio.

I first installed the new dongle firmware, this worked as described. After installing the new RRCMicro-Software I get the message "Value of '20' is not valid for 'Value'. 'Value' should be between "Minimum' and 'Maximum'. Parameter name: Value"

Hei, I have same problem. I upgraded RRC-Micro to 1.10.0 and uploaded firmware to dongle and now it's not working anymore. Any ideas how to fix it?PC has windows 10 on it.same error message."Value of '20' is not valid for..."

Thanks....I got the RRC Micro program working. I have upgraded the RRC-Radio to v. 2.91.

I cannot get the system to work. When I press either side of the paddles (which are plugged into the AUX port of the dongle), nothing happens. Is there a setting that I must set to get Bk-in TX? I have enabled the paddles in RRC Micro.

*** UPDATE ****

I removed the program again, and in device manager uninstalled the serial ports. Then I reinstalled RRC Micro. It now transmits when using the paddles. However, the iambic mode A does not work properly. Characters are not completed as in mode A.

**** 2nd UPDATE ****

Everything seems to work in Iambic Mode B.........band is dead right now, so no one is answering, but I am seeing myself on Reverse Beacon Network. Looks like we are in business once the band comes up. :-)

Fine!

And how about others? Have you been successful in making it work?

Always include type of hard/software and version when asking for support.

I have made quite a few QSO's with it so far. It appears that it works best with the WPM < 20. Above that, the sidetone 'clicking' gets bad and overpowers part of the sidetone and makes sending difficult.

Charlie KB8CR found the reason for the error I was encountering. It was because I used the .zip file and not the .bin file! Operator error.Sorry for the bandwidth. Thanks again Charlie! Appreciate your help.

For the keyer function. Would it also be possible to add Iambic Ultimatic, in addition to mode A and B?I learned CW with and Ultimatic keyer decades ago and trouble using anything else as this is also a mode on the winkeyers, but using a winkeyer is obviously no option here so support for Ultimatic would be greatly appreciated!
